TECHNICAL FIELD

The present disclosure relates to communications and, specifically, to amethod and device for determining time-frequency resources.

BACKGROUND

In the related art, in a new radio (NR) system, it has been determinedcurrently that a base station can semi-statically configure someresource sets. Resources in these resource sets can be dynamicallymultiplexed to a physical downlink shared channel (PDSCH) transmission,and specifically resources of which resource sets can be multiplexed tothe PDSCH transmission is indicated through dynamic signaling.

In the related art, in a physical downlink control channel (PDSCH) of aLong Term Evolution (LTE) system, a frequency domain will be mapped to afull bandwidth, and the number of orthogonal frequency divisionmultiplexing (OFDM) symbols occupied by the PDCCH in a time domain isindicated through a physical control format indicator channel (PCFICH).Therefore, a PDCCH domain is a frequency domain full bandwidth, the timedomain occupies a structure of several OFDM symbols in front of asub-frame, time-frequency resources of the PDCCH domain are completelyseparated from time-frequency resources of the PDSCH domain, andresources in the PDCCH domain cannot be used for the PDSCH transmission.

In an LTE enhanced PDCCH (ePDCCH), the ePDCCH is transmitted on aphysical resource block (PRB) set, that is, the ePDCCH and the PDSCHadopt a frequency division multiplexing mode. Resources in the PRB setare not used for the ePDCCH transmission but still can be used for thePDSCH transmission, and a “Resource Block assignment” domain in downlinkcontrol information (DCI) may include an indication for this part ofresources, so that a terminal may know allocation of all resources forthe PDSCH transmission.

For an NR PDCCH, based on several current discussions of 3GPP RANIconferences, the design will be performed based on a control resourceset (referred to as CORESET for short). Different from a characteristicof full bandwidth distribution in the LTE PDCCH, the distribution ofdownlink control channels in the NR is limited by CORESET(s) configuredby the system, the CORESET is semi-statically configured while userscheduling itself is dynamically changed, so when idle resources remainin the CORESET, in order to avoid resource waste, these resources can beused for the PDSCH transmission. Therefore, how to indicate multiplexedCORESET resources to a user to let the user know that there is a PDSCHservice on these control resources is a problem to be solved.

Furthermore, the 3GPP RANI has approved that the base stationsemi-statically configures several resource sets to dynamically indicatewhether resources in the resource set can be multiplexed to thescheduled PDSCH transmission or whether the scheduled PDSCH transmissionneeds to perform rate matching on part of resources of the resource set.

No efficient solution has been provided to solve the problem in therelated art of how to indicate time-frequency resources used by thePDSCH transmission.

The present disclosure will be described below in conjunction withexemplary embodiments.

Embodiment One

The base station semi-statically configures multiple resource sets forthe terminal and may configure the multiple resource sets through RRCsignaling. Time-frequency resources of the multiple configured resourcesets do not overlap.

When the base station configures resource sets for the terminal, thebase station needs to configure time-frequency resources occupied by theresource sets in a time-frequency resource unit, and also needs toconfigure time-frequency resource units in which the resource setsappear or time-frequency resource units in which the terminal monitorsthe resource sets. The time domain configuration in the time-frequencyunit may be configured through at least one of the following: a period,a time unit offset and a time unit pattern. The frequency domainconfiguration of the time-frequency resource unit may be configuredthrough at least one of the following: a carrier, a bandwidth part (BWP)in the carrier, several RBGs on the BWP in the carrier and several PRBson the BWP in the carrier.

If the base station does not configure the time-frequency resource unitin which the resource sets appear, the terminal may consider that theresource sets appear in each time-frequency resource unit, or theterminal needs to monitor the resource sets in all time-frequencyresource units.

Embodiment Two

The base station semi-statically configures multiple resource sets forthe terminal and may configure the multiple resource sets through RRCsignaling. Time-frequency resources of the multiple configured resourcesets may overlap. The overlap herein may be partial overlap, or may becomplete overlap. FIG. 2 is a schematic diagram of partial overlap orcomplete overlap according to an exemplary embodiment. As shown in FIG.2, from left to right, complete overlap, partial overlap and completeoverlap are shown respectively.

When the base station configures the resource sets, the base station mayindicate a priority of each resource set or priorities of resource setswhere resources overlap in an explicit or implicit manner.

As an example, the explicit manner may be to pre-configure by a systemor semi-statically configure a priority sequence number x of theresource set, where x is an integer, and priority sequence numbers fromsmall to large indicate that priorities are from high to low, orpriority sequence numbers from large to small indicate that prioritiesare from high to low.

In another example, the explicit manner may be to pre-configure by asystem or semi-statically configure resource sets meeting acharacteristic 1 as high priorities and remaining resource sets failingto the characteristic 1 as low priorities.

The characteristic 1 may be, but is not limited to, one of thefollowing: a resource set containing all or part of time-frequencyresources meeting a characteristic 2; and a resource set whoseconfiguration manner meets a characteristic 3.

The characteristic 2 may be, but is not limited to, one of thefollowing: being a specific or dedicated time-frequency resource, suchas a time-frequency resource occupied by a certain reference signal(RS), which for example, may be a synchronizing signal, a channel stateindication-RS (CSI-RS), a sounding reference signal (SRS), ademodulation reference signal (DMRS), a phase tracking reference signal(PTRS), etc., and a time-frequency resource occupied by a certain publicchannel, which for example, may be a physical broadcast channel (PBCH),a channel bearing system information, etc.; and being a reservationresource.

The characteristic 3 may be, but is not limited to, one of thefollowing: containing a certain configuration granularity, such asresource element (RE)-level configuration granularity and a resourceblock (RB)-level configuration granularity; configuration signalingbeing a certain specific format; and configuration signaling being acertain specific length or greater than a certain length.

The implicit manner may be that a resource set index itself represents apriority sequence, the resource set indexes from low to high representthat priorities are from high to low, or the resource set indexes fromhigh to low represent that priorities are from high to low.

When the dynamic signaling indicates whether a PDSCH resource needs toperform rate matching on the resource set or part of resources of theresource set, for multiple resource sets where resources overlap, ifdynamic signaling indications of the multiple resource sets areconsistent, that is, their dynamic signaling indications all indicatethat rate matching needs to be performed or the rate matching does notneed to be performed, the rate matching of the PDSCH is performedaccording to the dynamic signaling indications; and if their dynamicsignaling indications are inconsistent, rate matching needs to beperformed on some resource sets or part of resources thereof, and ratematching does not need to be performed on some resource sets or part ofresources thereof, which is determined according to indications of theresource sets with high priority or part of resources thereof. Whetherrate matching needs to be performed is determined based on theindication of the resource sets with high priority or part of resourcesthereof.

Embodiment Three

The base station semi-statically configures multiple resource sets forthe terminal and may configure the multiple resource sets through RRCsignaling.

The base station sends a dynamic signaling indication to the terminal toindicate a PDSCH transmission corresponding to a certain scheduling,resources of which resource sets may be occupied by the overlappedPDSCH, that is, rate matching does not need to be performed, andresources of which resource sets cannot be occupied by the PDSCH, thatis, rate matching needs to be performed.

For multiple resource sets where resources overlap, if dynamic signalingindications are different, then for the overlap area, as long as thedynamic signaling indication of at least one of resource sets indicatesthat rate matching does not need to be performed, rate matching of thePDSCH does not need to be performed on the overlap area. Only whendynamic signaling indications of all resource sets where overlappingoccurs indicate that rate matching needs to be performed, rate matchingof the PDSCH needs to be performed on the overlap area.

If a dynamic signaling indication corresponding to a certain resourceset being set to “1” indicates that rate matching does not need to beperformed and the dynamic signaling indication being set to “0”indicates that rate matching needs to be performed, for the overlap areaof multiple resource sets, a OR operation is performed according to thedynamic signaling indication of each resource set which belongs to theoverlap area, and whether resource multiplexing or rate matching needsto be performed on the overlap area is determined according to resultsof the OR operation: if the result of the OR operation is “1”, ratematching does not need to be performed on the overlap area, and if theresult of the OR operation is “0”, rate matching needs to be performedon the overlap area.

If a dynamic signaling indication corresponding to a certain resourceset being set to “1” indicates that rate matching needs to be performedand the dynamic signaling indication being set to “0” indicates thatrate matching does not need to be performed, for the overlap area ofmultiple resource sets, an AND operation is performed according to thedynamic signaling indication of each resource set which belongs to theoverlap area, and whether resource multiplexing or rate matching needsto be performed on the overlap area is determined according to resultsof the AND operation: if the result of the AND operation is “0”, ratematching does not need to be performed on the overlap area, and if theresult of the AND operation is “1”, rate matching needs to be performedon the overlap area.

In this embodiment, FIG. 3 is a schematic diagram of a dynamicindication manner according to an exemplary embodiment of the presentdisclosure. As shown in FIG. 3, a black block in Resource set 1 denotesa PDCCH scheduling the PDSCH. For a PDCCH resource scheduling the PDSCH,regardless of whether the PDSCH needs to perform rate matching on otherresources of a resource set where the PDCCH resource is located, thePDSCH needs to perform rate matching around time-frequency resourcesoccupied by the PDCCH scheduling the PDSCH. In addition, if the terminalblindly detects a common PDCCH or a group-common PDCCH in a certainresource set, regardless of whether the PDSCH needs to perform ratematching on the resource set, the PDSCH needs to perform rate matchingaround time-frequency resources occupied by at least one of the commonPDCCH and the group-common PDCCH.

Embodiment Four

The base station semi-statically configures multiple resource sets forthe terminal and may configure the multiple resource sets through RRCsignaling.

The base station sends a dynamic signaling indication to the terminal toindicate a PDSCH transmission corresponding to a certain scheduling,resources of which resource sets may be occupied by the overlappedPDSCH, that is, rate matching does not need to be performed, andresources of which resource sets cannot be occupied by the PDSCH, thatis, rate matching needs to be performed. The dynamic signalingindication may be valid on part of OFDM symbols of one slot.

FIG. 4 is a schematic diagram according to an embodiment 4. As shown inFIG. 4, a PDCCH scheduling the PDSCH is sent in Resource set 1, and adynamic signaling indication indicating whether the PDSCH multiplexesresources of the semi-statically configured resource sets is sent inthis PDCCH or another PDCCH. Assuming that the dynamic signalingindication for Resource set 1 is “1”, which indicates that all or partof time-frequency resources of Resource set 1 may be multiplexed by thePDSCH, the PDSCH does not need to perform rate matching on all or partof time-frequency resources of Resource set 1. When a dynamic signalingindication of Resource set 2 is “0”, which indicates that all or part oftime-frequency resources of Resource set 2 may not be multiplexed by thePDSCH, the PDSCH needs to perform rate matching on all or part oftime-frequency resources of Resource set 2.

Resource set 1 and Resource set 2 have their own monitor occasionconfiguration. The monitor occasion configuration of Resource set 1 isin a slot level. For example, each slot needs to be monitored or eachseveral slots need to be monitored. One slot only has one monitoroccasion at most. The monitor occasion configuration of Resource set 2is in a min-slot level or an OFDM symbol level, and one slot may havemultiple monitor occasions.

The dynamic signaling indications of Resource set 1 and Resource set 2are valid on only one monitor occasion. For example, the monitoroccasion may be a first monitor occasion where Resource set 1, Resourceset 2 and resource allocation of the PDSCH overlap in a slot where aPDSCH transmission corresponding to the dynamic signaling indication islocated. Using FIG. 4 as an example, for Resource set 1, the validmonitor occasion is Occasion 1 of Resource set 1, and for Resource set2, the valid monitor occasion is Occasion 1 of Resource set 2.

Embodiment Five

Still using FIG. 4 as an example, in a corresponding resource set, thedynamic signaling indications of Resource set 1 and Resource set 2 arevalid on all monitor occasions which overlap resource allocation of acorresponding PDSCH. For example, the all monitor occasions may be allmonitor occasions where Resource set 1, Resource set 2 and resourceallocation of the PDSCH overlap in a slot where a PDSCH transmissioncorresponding to the dynamic signaling indication is located. Using FIG.4 as an example, for Resource set 1, the valid monitor occasion isOccasion 1 of Resource set 1, and for Resource set 2, the valid monitoroccasion is Occasion 1 and Occasion 2 of Resource set 2.

Embodiment Six

FIG. 5 is a schematic diagram according to an embodiment 6. As shown inFIG. 5, in a corresponding resource set, the dynamic signalingindications of Resource set 1 and Resource set 2 are valid on allmonitor occasions which overlap resource allocation of a correspondingPDSCH. A PDCCH domain usually is first several OFDM symbols of one slot.In the PDCCH domain, dynamic signaling indications are valid on allmonitor occasions where Resource set 1, Resource set 2 and resourceallocation of the PDSCH overlap. Using FIG. 5 as an example, forResource set 1, the valid monitor occasion is Occasion 1 of Resource set1, and for Resource set 2, the valid monitor occasion is Occasion 1 andOccasion 2 of Resource set 2. Occasion 3 also overlaps resourceallocation of the PDSCH, but since Occasion 3 is not within the PDCCHdomain, the dynamic signaling indication is not valid in Occasion 3 ofResource set 2.

Embodiment Seven

Still using FIG. 4 as an example, for the dynamic signaling indicationsof Resource set 1 and Resource set 2, their valid ranges are related tothe blind detection of the terminal. For example, in a correspondingresource set, the dynamic signaling indications are valid on a firstmonitor occasion which overlaps resource allocation of a correspondingPDSCH. In FIG. 4, the first monitor occasion in Resource set 1 isOccasion 1, and the first monitor occasion in Resource set 2 is Occasion1. For other monitor occasions which overlap resource allocation of thePDSCH, for example, Occasion 2 of Resource set 2 in FIG. 4, whether thedynamic signaling indication is valid depends on results of the blinddetection performed by the terminal on the resource set in acorresponding monitor occasion.

The blind detection includes the following.

1) If the terminal does not blindly detect a PDCCH sent by the basestation to the terminal itself on a corresponding occasion,

time-frequency resources of a corresponding resource set on thisoccasion, which overlap resource allocation of a corresponding PDSCH,may be used for the PDSCH transmission, that is, the terminal does notneed to perform rate matching on the PDSCH in correspondingtime-frequency resources, which is not related to the dynamic signalingindication; or the indication of the dynamic signaling indication forthis resource set continues to be valid.

2) If the terminal detects the PDCCH sent by the base station to theterminal itself on a corresponding occasion,

a corresponding resource set cannot be used for the PDSCH transmissionon this occasion, that is, the terminal needs to perform rate matchingon the PDSCH in corresponding time-frequency resources, which is notrelated to the dynamic signaling indication.

Alternatively, in the corresponding resource set on this occasion, whenthe terminal blindly detects resources other than time-frequencyresources occupied by the PDCCH, the indication of the dynamic signalingindication for this resource set continues to be valid.

Embodiment Eight

Using FIG. 5 as an example, for the dynamic signaling indications ofResource set 1 and Resource set 2, their valid ranges are related to theblind detection of the terminal. For example, in a correspondingresource set, the dynamic signaling indication is valid on all monitoroccasions which overlap resource allocation of a corresponding PDSCH. InFIG. 5, the valid monitor occasion in Resource set 1 is Occasion 1, andthe valid monitor occasion in Resource set 2 is Occasion 1 and Occasion2. For other monitor occasions which overlap resource allocation of thePDSCH, for example, Occasion 3 of Resource set 2 in FIG. 5, whether thedynamic signaling indication is valid depends on results of the blinddetection performed by the terminal on the resource set on acorresponding monitor occasion.

The result of the blind detection is as follows.

1) If the terminal does not blindly detect a PDCCH sent by the basestation to the terminal itself on a corresponding occasion,

time-frequency resources of a corresponding resource set on thisoccasion, which overlap resource allocation of a corresponding PDSCH,may be used for the PDSCH transmission, that is, the terminal does notneed to perform rate matching on the PDSCH in correspondingtime-frequency resources, which is not related to the dynamic signalingindication; or the indication of the dynamic signaling indication forthis resource set continues to be valid.

2) If the terminal detects the PDCCH sent by the base station to theterminal itself on a corresponding occasion,

a corresponding resource set cannot be used for the PDSCH transmissionon this occasion, that is, the terminal needs to perform rate matchingon the PDSCH in corresponding time-frequency resources, which is notrelated to the dynamic signaling indication.

Alternatively, in the corresponding resource set on this occasion, whenthe terminal blindly detects resources other than time-frequencyresources occupied by the PDCCH, the indication of the dynamic signalingindication for this resource set continues to be valid.

FIG. 6 is a schematic diagram according to an embodiment 9. As shown inFIG. 6, when a PDSCH scheduled in Resource set 1 occupies multipleslots, a multiplexing resource dynamic signaling indication which issent by the base station to the terminal and corresponds to the PDSCHtransmission is only valid in a first slot of resource allocation of thePDSCH, and is invalid in other slots of resource allocation of thePDSCH, that is, in FIG. 5, the dynamic signaling indication of Resourceset 1 and Resource set 2 are only valid in Slot 1 and invalid in Slot 2.

Embodiment Ten

As shown in FIG. 6, when the PDSCH scheduled in Resource set 1 occupiesmultiple slots, a multiplexing resource dynamic signaling indicationwhich is sent by the base station to the terminal and corresponds to thePDSCH transmission is valid in all slots included in resource allocationof the PDSCH, that is, in FIG. 5, the dynamic signaling indication ofResource set 1 and Resource set 2 are valid in both Slot 1 and Slot 2.

Embodiment Eleven

As shown in FIG. 6, when the PDSCH scheduled in Resource set 1 occupiesmultiple slots, a multiplexing resource dynamic signaling indicationwhich is sent by the base station to the terminal and corresponds to thePDSCH transmission is valid in a first slot of resource allocation ofthe PDSCH, that is, this indication is valid in Slot 1 in FIG. 5; forother slots included in resource allocation of the PDSCH, that is, Slot2 in FIG. 5, dynamic signaling 2 is required to be indicate. Accordingto the indication of the dynamic singling 2, whether a correspondingresource set in Slot 2 may be multiplexed the PDSCH scheduled inResource set 1 is determined. The dynamic singling 2 may be one of thefollowing:

an indication indicating activation/inactivation of a dynamic signalingindication sent in Slot 1; and

a new dynamic signaling indication, which is not related to the dynamicsignaling indication sent in Slot 1, where an indicated resource set maybe different from the dynamic signaling indication sent in Slot 1.

Embodiment Twelve

When a gNB configures time-frequency resources of a resource set, if oneresource set contains multiple CORESETs, monitor occasions of themultiple CORESETs configured in the same resource set should meet acertain requirement. The requirement may be one or a more of thefollowing:

1) a monitor occasion configuration of each CORESET is totally the same,that is, the CORESET is blindly detected on the same radio frame orsub-frame or slot or OFDM symbol;

2) a monitor occasion configuration level of each CORESET is the sameand is a slot level, for example, the CORESET may be blindly detected oneach slot or every multiple slots;

3) a monitor occasion configuration level of each CORESET is the sameand is a mini-slot level, for example, the CORESET may be blindlydetected on each mini-slot or every multiple mini-slots;

4) a monitor occasion configuration level of each CORESET is the sameand is an OFDM symbol level, for example, the CORESET may be blindlydetected on each OFDM symbol or every multiple OFDM symbols; and

5) a monitor occasion configuration of each CORESET needs to meet aninclusion relationship, for example, for a CORESET with a sparse numberof times of blind detections and a CORESET with an intensive number oftimes of blind detections, blind detection moment of the former is asubset of blind detection moment of the latter. As shown in FIG. 7,CORESET 1 and CORESET 4 are configured in the same resource set, andsince the monitor occasion of CORESET 1 is each slot while the monitoroccasion of CORESET 4 is each odd slot, the monitor occasion of CORESET4 is a sub-set of the monitor occasion of CORESET 1. CORESET 2 andCORESET 3 may be configured in the same resource set, and since themonitor occasion of CORESET 2 is OFDM symbols {0 2 5 12} of each slotwhile the monitor occasion of CORESET 3 is an OFDM symbol {5} of eachslot, the monitor occasion of CORESET 3 is a sub-set of the monitoroccasion of CORESET 2.

The number of times of appearance of the monitor occasion configurationof each CORESET in a fixed time unit is the same. For example, with oneslot as the fixed time unit, CORESETs whose monitor occasion appearsonce in one slot may be configured in the same resource set. As shown inFIG. 7, CORESET 1 and CORESET 3 may be configured in the same resourceset, because their monitor occasion appears once in one slot.

After a resource set containing multiple CORESETs is configuredaccording to the above rule, a dynamic signaling indication for thisresource set is valid in corresponding unit time, where the unit timemay be a sub-frame or multiple sub-frames, or a slot or multiple slots,or a PDCCH domain of one slot or PDCCH domains of multiple slots, or afixed number of OFDM symbols. In time-frequency resources which overlapresource allocation of the PDSCH, all monitor occasions of all CORESETsincluded in the resource set in the unit time follow the dynamicsignaling indication.

Alternatively, after one resource set containing multiple CORESETs isconfigured according to the above rule, the dynamic signaling indicationfor this resource set is valid on a single monitor occasion. The singlemonitor occasion may be time-frequency resources corresponding to afirst monitor occasion of each CORESET included in this resource set intime-frequency resources where the resource set overlaps resourceallocation of the PDSCH.

Embodiment Thirteen

The base station semi-statically configures multiple resource sets forthe terminal and may configure the multiple resource sets through RRCsignaling.

The base station sends a dynamic signaling indication to the terminal toindicate a PDSCH transmission corresponding to a certain scheduling,resources of which resource sets may be occupied by the overlappedPDSCH, that is, rate matching does not need to be performed, andresources of which resource sets cannot be occupied by the PDSCH, thatis, rate matching needs to be performed.

For the overlap area of multiple resource sets, the base station mayconfigure a principle to determine whether the scheduled PDSCHtransmission performs rate matching on the overlap area. The principlemay be configured through RRC signaling or system informationsemi-statically or through the PDCCH dynamically.

For the overlap area of multiple resource sets, different principles maybe adopted to determine whether the scheduled PDSCH transmissionperforms rate matching on the overlap area. For example, for differentconfiguration manners or a resource set containing different types oftime-frequency resources, different principles may be adopted. FIG. 8 isa schematic diagram 1 according to an embodiment thirteen. As shown inFIG. 8, when Resource set 1 and Resource set 2 are configured in aconfiguration manner 1 or configured as resource sets containing thetype 1 of time-frequency resources and Resource set 3 is configured in aconfiguration manner 2 or configured as a resource set containing thetype 2 of time-frequency resources, for an overlap area OA1 of Resourceset 1 and Resource set 2, whether the PDSCH needs to perform ratematching on OA1 is determined according a principle 1, and for anoverlap area OA2 of Resource set 1 and Resource set 3, whether the PDSCHneeds to perform rate matching on OA2 is determined according aprinciple 2.

The principle 1 and the principle 2 may be one of the following.

1) In resource sets where overlapping occurs, as long as one resourceset is indicated by the dynamic singling indication to be unable to bemultiplexed by the PDSCH, the PDSCH needs to perform rate matching onthe resource sets, and regardless of whether the PDSCH needs to performrate matching on other resource sets, the overlap area cannot bemultiplexed by the PDSCH, and the PDSCH needs to perform rate matchingon the overlap area.

2) In resource sets where overlapping occurs, as long as one resourceset is indicated by the dynamic singling indication to be able to bemultiplexed by the PDSCH, the PDSCH does not need to perform ratematching on the resource sets, and regardless of whether the PDSCH needsto perform rate matching on other resource sets, the overlap area can bemultiplexed by the PDSCH, and the PDSCH does not need to perform ratematching on the overlap area.

3) According to resource set priorities semi-statically configured orpre-configured by a system or resource set priorities which areequivalent to priorities semi-statically configured or pre-configured bythe system, when a resource set having a high priority overlaps aresource set having a low priority, a dynamic signaling indication ofthe resource set having a high priority is followed to determine whetherthe overlap area can be multiplexed by the PDSCH and whether the PDSCHneeds to perform rate matching on the overlap area.

Embodiment Fourteen

The dynamic singling indication may contain one or more bits forindicating whether one or more resource set time-frequency resources canbe used by the scheduled PDSCH transmission or whether the scheduledPDSCH transmission needs to perform rate matching on resource settime-frequency resources. The resource set indicated by a certain one ormultiple bits in the dynamic signaling indication may be semi-staticallyconfigured, or may be dynamically changed.

FIG. 9 is a schematic diagram 1 according to an embodiment fourteen. Asshown in FIG. 9, when the resource set is configured semi-statically,the base station may configure an x-th bit or bit group in dynamicsignaling indications corresponding to Resource 1 and Resource 2 andconfigure a y-th bit or bit group in a dynamic signaling indicationcorresponding to Resource set 3 through RRC signaling or systeminformation, where x and y are positive integers not greater than alength of the dynamic signaling indication. In one slot, time-frequencyresources corresponding to Resource set 1 and Resource set 2 may be thesame or different, and may be semi-statically configured by the basestation through RRC signaling or system information. At least one of thefollowing parameters of Resource set 1 and Resource set 2 is different:a configuration period, a time domain offset and a monitor occasion, andthese parameters may also be semi-statically configured by the basestation through RRC signaling or system information. Therefore, the basestation, through RRC signaling or system information, maysemi-statically configure a time unit appearing in Resource set 1, thex-th bit or bit group corresponding to Resource set 1 in the dynamicsignaling indication, a time unit appearing in Resource set 2, the x-thbit or bit group corresponding to Resource set 2 in the dynamicsignaling indication, and the y-th bit or bit group corresponding toResource set 3 in the dynamic signaling indication.

As shown in FIG. 9, when the resource set is configured dynamically, thebase station may configure an x-th bit or bit group in dynamic signalingindications corresponding to Resource 1 and Resource 2 and configure ay-th bit or bit group in a dynamic signaling indication corresponding toResource set 3 through RRC signaling or system information, where x andy are positive integers not greater than a length of the dynamicsignaling indication. In one slot, time-frequency resourcescorresponding to Resource set 1 and Resource set 2 may be the same ordifferent, and may be semi-statically configured by the base stationthrough RRC signaling or system information. At least one of thefollowing parameters of Resource set 1 and Resource set 2 is different:a configuration period, a time domain offset and a monitor occasion, andthese parameters may also be semi-statically configured by the basestation through RRC signaling or system information. According to theconfiguration of the base station, when the terminal may determine thatonly Resource set 1 or Resource set 2 exists in a certain time unitscheduled by the PDSCH (which may be a sub-frame or a slot or amini-slot or an OFDM symbol group), the resource set corresponding tothe x-th bit or bit group may be Resource set 1 or Resource set 2, andthe y-th bit or bit group in the dynamic signaling set alwayscorresponds to Resource set 3.

Configurations of Resource set 1 and Resource set 2 may also be shown inFIG. 10. FIG. 10 is a schematic diagram 2 according to an embodimentfourteen. The x-th bit or bit group in the dynamic signaling indicationcorresponds to Resource set 1 in some time units (such as slots 1, 3 and5) or corresponds to Resource set 1 and Resource set 2 in some timeunits (such as slots 2,4 and 6), that is, a resource set index as wellas the number of resource sets corresponding to the x-th bit or bitgroup may be different, and may also be semi-statically configured ordetermined by the terminal according to the configuration of theresource set.

Embodiment Fifteen

When the base station configures a length of dynamic signaling to be mbits and configures the number of candidate multiplexed resource setsthat the dynamic signaling needs to indicate to be m+1, which resourceset the m bits of the dynamic signaling correspond to depends on aresource set stored in a certain time unit and a resource set whichoverlaps resource allocation for the scheduled PDSCH transmission.

Using m=2 as an example, the length of the dynamic signaling is 2 bits,and the number of candidate multiplexed resource sets is 3, which aremarked as Resource set 1, Resource set 2 and Resource set 3respectively.

If these three resource sets exist in a certain time unit and alloverlap resource allocation of the PDSCH transmission scheduled by thecurrent time unit, one of the following manners or a combination thereofis adopted.

According to a sequence order or priority order of the resource sets,2-bit dynamic signaling cannot indicate the multiplexing of the lastresource set, that is, the terminal considers by default that the lastresource set cannot be multiplexed by the PDSCH and the PDSCH needs toperform rate matching on the last resource set.

According to a sequence order or priority order of the resource sets, 1bit in the dynamic signaling indication is used for jointly indicatingthe multiplexing of last two resource sets, that is, both the last tworesource sets are multiplexed or the both are not multiplexed.

If in a certain time unit, the number of resource sets that overlapresource allocation of the PDSCH transmission scheduled by the currenttime unit is 2, 2 bits of the dynamic signaling indicate the tworesource sets respectively.

If in a certain time unit, the number of resource sets that overlapresource allocation of the PDSCH transmission scheduled by the currenttime unit is less than 2, for example, 1, redundant bits exist in thedynamic indication signaling.

Embodiment Sixteen

When there is redundancy in the number of bits contained in dynamicindication signaling transmitted by a certain time unit compared to thenumber of resources sets that the current time unit needs to indicate,redundant bits may have one of functions or a combination thereof.

The redundant bits are used for indicating multiplexing or rate matchingafter at least one of a time domain, a frequency domain and a spacedomain of a resource set corresponding to an adjacent bit or bit groupis split.

The redundant bits are used for indicating multiplexing or rate matchingafter at least one of a time domain, a frequency domain and a spacedomain of a specific resource set is split. The specific resource setmay be a resource set that the terminal needs to monitor, or a resourceset of a PDCCH receiving the scheduled PDSCH transmission, or a resourceset sent by the dynamic signaling indication, or a specific resource setsemi-statically configured by the base station.

The redundant bits are used for indicating multiplexing or rate matchingafter at least one of a time domain, a frequency domain and a spacedomain of every other resource set corresponding to all other adjacentbits or bit groups is split.

The redundant bits are used for indicating whether activation anddeactivation or handover of a carrier or a BWP occur in a subsequenttime unit. The split is that at least one of a time domain, a frequencydomain and a space domain of a corresponding resource set is equallysplit and may be equally split into n part according to the number ofredundant bits, where n is a positive integer, and after the equal splitis performed, non-redundant bits and redundant bits jointly indicatewhich equally split parts of the corresponding resource set are capableof being multiplexed to the PDSCH transmission, or the PDSCH does notneed to perform rate matching on which equally split parts.

The redundant bits are used for indicating whether a length of a dynamicsignaling indication sent by a subsequent time unit changes. Forexample, a state ‘0’ represents that the length does not change, and astate ‘1’ represents that the length changes. For example, the length isrecued or increased by z bits, where z may be equal to, but is notlimited to, the number of redundant bits or 1.

Embodiment Seventeen

The base station configures one or more resource sets for the terminal,where some resource sets are configured to contain one or more completeor partial CORESETs while configurations of other resource sets are notrelated to the CORESET, or although specific time-frequency resourcesoverlap the CORESET, the base station does not configure resource setswith specific CORESET sequences, but directly configures specifictime-frequency resources contained in the resource sets in an explicitmanner. During configuring, at least one of following resources may beconfigured: time domain resources contained in a time domain resourceunit, frequency domain resources contained in a frequency domainresource unit, a period and offset of a time domain resource unit in atime domain, and a period and offset of a frequency domain resource unitin a frequency domain.

For example, the time domain resource unit may be a slot or a sub-frame,and the base station configures a certain resource set for occupyingpart of OFDM symbols of the slot or sub-frame in a time domain resourceunit.

The frequency domain resource unit may be N PRBs, for example, 25 or 50PRBs, and the base station configures a certain resource set foroccupying part of PRBs of the N PRBs in a frequency domain resourceunit.

The period of the time domain resource unit in the time domain may beone or more time domain resource units. For example, if the period isconfigured as 2 slots, it means that in every 2 slots, part of OFDMsymbols of one slot is time domain resources of the resource set. Theoffset of the time domain resource unit in the time domain representsthat time domain resources of the resource set exist in a time domainresource unit (which one time domain resource depends to a value of theoffset) in a time domain period. If the offset is set to 1, it meansthat part of OFDM symbols of a first time domain resource unit in eachtime domain period is time domain resources of the resource set.

The period of the frequency domain resource unit in the frequency domainmay be one or more frequency domain resource units, and may be limitedto be one or more carried bandwidths or one or more BWPs of one carrierbandwidth. For example, if the period is set to 2 frequency domainresource units, it means that in every 2 frequency domain resourceunits, part of PRBs of one frequency domain resource unit is frequencydomain resources of the resource set. The offset of the frequency domainresource unit in the frequency domain represents that frequency domainresources of the resource set exist in a frequency domain resource unit(which one frequency domain resource unit depends on a value of theoffset) in one frequency domain period. If the offset is set to 1, itmeans that part of PRBs of a first frequency domain resource unit ineach frequency domain period is frequency domain resources of theresource set.
